Title: Perforated flat metal heat pipe
Inventor: AKACHI HISATERU
IPC: F28D15/02
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain a perforated flat metal heat pipe exhibiting high performance comparable to that of a heat exchanger employing a thin meandering heat pipe by effectively utilizing an extremely inexpensive perforated flat pipe obtained through extrusion molding of light metal, and to utilize its unique function while reducing the cost significantly. SOLUTION: A perforated flat pipe has opposite end faces sealed by welding and thin hole groups are coupled, respectively, each other at parts proximate to the opposite ends by a specified means. A working liquid is then encapsulated to obtain a thin diameter tunnel heat pipe and the flat pipe thereof is reshaped to reciprocate, while snaking, between a high temperature part and a low temperature part a large number of times thus constituting a heat exchanging part. A high performance heat exchanger can thereby be realized based on the same principle as snaking thin heat pipe. Since one flat pipe exhibits a performance corresponding to several tens of thin pipes, material cost and assembling cost can be reduced by one-tenth. Furthermore, weight of the heat exchanger can be reduced through simple and strong structure and the reliability is enhanced significantly.
